Question

A toy boat is released at point A into a river 0.1 km wide. The boat propels itself at a constant 2 km/hr in a direction perpendicular

to the shore. The velocity (in KM/Hr) of the current in the river is given

by the equation V_C = 200(y-10y^2) where y is the distance from the shore at

A (in km). What distance x is the boat downstream when it reaches the other

side of the river? Dynamics problem - This is looking for dostance x, not distance y!!!
